HOSE-COUPLING.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application led December l, 1905. Serial No. 289,831.

To all whom, it may concern:

Be it known that I, JOHN T. LALLY, a citi- Zen of the United States, residing at Wil-4 mington, Delaware, have invented certain Improvements in Hose-Couplings, of which the following is a specification.

The object of my invention is yto provide means by which one part of a hose-coupling can be readily detached from another. This obj ect I attain in the following manner, reference being had to the accompanying draw ings, in which- I.

Figure l is a perspective view of a hosecoupling illustrating my invention. Fig. 2 is a view similar to Fig. l, showing the coupling partly detached. Fig. 3 is a longitudinal sectional view through the coupling with the latches in engagement. Fig. 4 is a view of part of Fig. 3, showing a latch disengaged.

Fig. 5 1s a perspective view of the operatinglever, and Fig. 6 is a section through the latch and lever on the line 6 6, Fig. l.

A is one portion of the hose-coupling, and B is the other portion, each connected to hose-sections A and B', respectively. These portions are made in the ordinary manner, the portion B having an annular flange I), with which engage the hooked ends d d of the latches D D, which are pivoted at d2 d3, respectively, to the portionA of the coupling. Carried by the portion A in the present instance is a gasket e, of rubber or other suitable material, for making a tight joint between the two parts.

All the above-described mechanism is common to the ordinary hose-coupling but couplings of this type have to be detached usually by means of what is termed a hose-hook, which is so inserted between the nose of the latch and the portion B as to lift the latch free of the flange b. This hose-hook is objectionable for many reasons.

Means have been provided for releasing the latches; but these means are usually cumbersome and project above the body portion in such a manner as to be either broken off, owing to the rough usage to which firehose is subjected, or become unlatched by the projecting portions engaging the pavement or other obstructions.

I pivot at c to the latch D a lever E, which has a cam-face c which bears against the flange a of the portion A when the lever is raised to the position shown in Fig. 4. The

handle portion e2 of the lever extends rearwardly and is shaped to be engaged by the fingers of the operator, and the lever is also so shaped that when it is in the position shown in Figs. l and 3 the nose d of the latch D is in engagement with the flange l) of the portion B ol" the coupling. When the lever is raised to the position shown in Fig. 4, it turns the latch D on its pivot, so that the nose d of the latch will be free of the flange. A

spring c is wrapped around each pivot-pinl d2 d3, and the projecting ends are so arranged that they will cause the latches to remain normally in the closed position, as illustrated in Fig. 3. There is also a spring f on the pivot-pin e of the lever E, so that the normal position of the lever is closed, as showni in.

Figs. l and 3.

It is only necessary latches with the operating-lever, as when the lever is operated as in Fig. 2 all that is necessary is to turn the portion B of the coupling on the latch D/ until it is free after the latch D has been drawn away by its lever.

It will be noticed in the drawings that the latch D has a central groove i, as shown in Fig. 2, and the lever E when in the position shown in Fig. l fits in this groove, so that its upper surface will be flush with the surface of the latch.

In order to prevent sticking of the lever by bruising of the parts, I preferably bevel the edges of the lever as well as the latch on each side of the' opening, as shown in Fig. 6, so that any burring of the parts will not lock the two together.

The lever is longer than the latch, extending sufficiently in the rear of it so that the fingers can engage the latch, and the flange a2 of the coupling A, which protects the latch, is cut away at a3 to allow for the entrance ofthe iingers that they can readily engage the end of the lever.

It will be noticed that there is a ilange a4 at the rear of the eXtreme end of the lever which protects this lever and prevents it becoming to provide one of4 the- IOC accidentally raised, and there are slight projections a5 at each end of this flange which protect the flange from being burred.

Thus it will be seen that by my invention I am enabled to provide a simple and effective means for readily releasing the latch of a hose-coupling which will be entirely protected, so that the latch cannot be accidentally disengaged, and so arranged that any burring or bruising of the coupling will not affect the operation of the lever.

I claiml. The combination in a hose-coupling, of a spring-latch pivoted to one part and engaging the other part, a lever pivoted to the nose end of the latch and arranged to force the latch out of engagement with the other part of the coupling, the lever being mounted in a recess in the latch and a recess in the casing, so as to be protected, substantially as described.

2. The combination in a hose-coupling, of `a spring-latch pivoted to one portion of the coupling and engaging a flange on the other portion of the coupling, said latch having a longitudinal recess, a lever mounted in the recess and pivoted to the nose end of the latch, and a protecting-flange on the coupling, the lever being so arranged that it will not extend beyond the surface of the latch and flange, substantially as described.

3. The combination in a hose-coupling, of two parts, a lever pivoted to one part and engaging a flange on the other part, said latch having a recess therein, a lever mounted in said recess Vand pivoted to the latch in such a position that it will raise the latch when operated, said lever extending beyond the end of the latch, the body of the coupling having finger-openings and a flange protecting the rear of the latch, substantially as described.

4. The combination in a hose-coupling, of t'Wo portions, a latch pivoted to one portion, a spring for keeping the latch normally closed, said latch arranged to engage a flange on the other portion, a central recess in the latch, a lever mounted in the central recess and pivoted to the nose end of the latch, a

spring for said lever, said lever extending rearwardly beyond the end of the latch and having a finger-hold, and a flange forming a recess at the rear of the latch for the reception of the end of the lever so that the lever will be rotected substantially as described.

5. T e combination in a hose-coupling, of a spring-latch pivoted to one ortion of the hose-coupling and engaging tlie other portion, a lever pivoted to the nose end of the latch and arranged to force the latch out of engagement with the other part of the coupling, the lever being mounted in a recess and pivoted to the nose end pf the latch, a protecting-flange on the coupling, the lever being so arranged that it will not extend beyond 'the surface of the latch and flange, the edge of the latch on each side of the recess being beveled and the outer edges of the lever also being beveled so as to prevent the locking of the lever to the latch by burring ofthe parts, substantially as described.

6. The combination in a hose-coupling, of two portions, a latch pivoted to one portion and engaging the other portion, a central lever mounted in a recess in the latch and pivoted to the latch, the handle end of the lever extending beyond the end of the latch, a projecting flange on the body portion of the coupling back of the lever and extending above the end of the lever, said flange having a projection at each end acting to protect the latch, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
